Go to the smartusa.com website. Look at the headline where the name of the site is.
It says "Open your mind to the car that challenges the status quo"
The Yaris is part of that status quo.
The smart is not.
Ultimately its your choice and your car, so you should pick whatever is best for your needs.
However almost everyone on this site has chosen to go away from that status quo, so to expect us to agree with you in some way is silly. Some of us might get riled up, but it's nothing that a ride in the little smart won't cure...
